SOLVED Weird. I can't ping from the Truenas Scale server a Windows VM hosted by the server itself

[titust1]

The Truenas Scale server is hosting a Windows VM. The VM obtains a DHCP address from my router, and is able to ping all the machines on the local network, except the Truenas Scale server. From the Truenas Scale server I can ping all machines on the LAN except the IP of the VM machine.
I don't get it...
Do I have to enable something on the Truenas Scale server network?
Please help

Yes thanks
This is the short form of the above documentation:

1. Go To Network / Edit the main Interface (NIC) / Uncheck DHCP or remove the IP from the NIC -> Apply (don't worry it's OK)
2. In Network Interfaces Click Add to create a bridge
   1. Specify the Type: Bridge
   2. Name: br0 (if it's the first one)
   3. Uncheck DHCP
   4. Select the primary NIC as only member to that bridge
   5. Assign to the bridge the IP formerly owned by the NIC
   6. Apply
3. Test Network Changes
4. Important Don't forget to save changes
5. Click on Virtualization
   1. Select VM
      1. Device / NIC Edit
      2. Bind to br0 (instead of the NIC)
      3. Apply

I have a VM for ubuntu plex and have a similar issue. I can't mount a drive on the same Truenas Scale server. I have 4 nics on my server so can I use a different nic for this VM and solve this issue?

Following the instructions provided by titust1, the network changes were removed after testing the network. I guess the test failed and changes were reverted. I see the errors in the syslog:

Looks like you're still running a VM... you need to set VMs to not autostart, Restart, then make the changes.

After rebooting my Linux system, and changed the NIC to bridge, I received some error messages as shown below.

CallError​

[EFAULT] VM will not start as NIC Device: br0 device(s) are not available.

Is that device available? (is it considered "UP" in ifconfig)
